This portion of the plowing experiment has addressed only the location of radioactive contamination
as measured by 24l14m. Inferences may be drawn as to the reduction in surface dose rate and
resuspension potential from this work. Changes in plant uptake of radioactive material due to
changes in radioactivity profile, risk due to future possible earthmoving operations in the area, and
the political question of dilution vs. removal of radioactive contamination have not been addressed.
